In collaboration with Philips Lighting, researchers from the FOM institutes AMOLF and DIFFER have found a way to switch the antenna effect of metal nanoparticles on and off. Nanoantennae are sensitive receivers and enhancers ...

(Phys.org)—A small team of researchers with the University of California and Rice University has created a model of chemotaxis that shows how individual cells may work together to respond to a chemical-concentration gradient. ...

The quantum world and our world of perception obey different natural laws. Leiden physicists search for the border between both worlds. Now they suggest an upper limit in a study reported in Physical Review Letters.

Some phenomena that appear to be well understood are much more mysterious than it seems. In spite of the numerous applications that rely on the presence or absence of bubbles, no advanced scientific studies had been carried ...

(Phys.org)—Quantum entanglement—which occurs when two or more particles are correlated in such a way that they can influence each other even across large distances—is not an all-or-nothing phenomenon, but occurs in ...

(Phys.org)—It may sound like a simple riddle, but a team of scientists is intrigued with the answer because it could lead to a better understanding of percolation, the process that occurs when a liquid trickles through ...

The sources of the high-energy cosmic neutrinos that are detected by the IceCube Neutrino Observatory buried in the Antarctic ice may be hidden from observations of high-energy gamma rays, new research reveals. These high-energy ...

(Phys.org)—Maxwell's demon, a hypothetical being that appears to violate the second law of thermodynamics, has been widely studied since it was first proposed in 1867 by James Clerk Maxwell. But most of these studies have ...
